I have an HP 3000 pro small form factor PC. I installed a new video card into it and it automatically disabled the onboard video card. I am currently using the video card for my monitors, but i need the internal video card enabled for connection to other devices like a projector.

How would i go about enabling the internal video card? I do not see the internal video card in device manager...

This is a function of the mainboard and BIOS, and most systems do not support running embedded graphics concurrently with add-on cards. If there is a setting in your BIOS graphics settings for Auto, this is probably the most likely to support what you're looking for.

I had this frustration myself recently. Older IBM Thinkcentre workstations like the 8215-23U could run both onboard and video card graphics. So I had a video card with 4 outputs, but only had to use two of them and then use the embedded/onboard graphics for the third monitor.

However, on the 9645-QMU, the 9964-A7U, and the 3269-B5U, all newer systems, this does not work at all. The BIOS disables the onboard graphics when a video card is used. It does not matter which type of card you use or what connector. PCI, PCI-e 1x (or 16x), AGP, it is the machine itself that determines if it can run onboard and add-on cards simultaneously.

This is normal on many systems. If you need more monitors then you'll either need to add a 2nd card or get another card that supports more monitors.

one of the reasons this function is inhibited on SFF PC's, is that the POWER Supply can not output enough power for an additional video card...

Hi,

I believe this device has either a 250 or 300 watt Power Supply unit.

In order to run an additional device, you'd need either:

1. A card supporting 3 concurrent video outputs - something like a Radeon HD5450 Eyefinity model (http://www.club-3d.com/index.php/products/reader.en/product/hd5450-eyefinity-edition.html?page=2)
2. An additional video card such as a PCI or USB video adapter (http://www.google.co.uk/products/catalog?hl=en&pq=detecting+mobile+browser+php&xhr=t&q=usb+video+adapter&cp=11&wrapid=tljp1300184224948018&um=1&ie=UTF-8&cid=6223460955087788850&sa=X&ei=pTx_TYCKBIyZhQf3vOGxBw&sqi=2&ved=0CDoQ8wIwAw#)
3. Drive 2 monitors from one of the video outputs using an adapter (http://www.matrox.com/graphics/en/products/gxm/dh2go/)

Regards,


RobMobility.

that point assignment is fine with me. sorry for the delay, but it is unfortunate there was no configuration based solution.
